its 16 months old with all new filters etc. and membranes the tmc one comes with a few bits and pieces is a 3 stage unit but I thought they retailed at about £125 the last time I looked
Not sure it comes with taps it will have a presure meter on it though it does not have a DI unit as its optional the osmotics ones are better if you want a 3 stage one you would be better of looking at the osmotics range
Just looked and spotted TMC do a cheaper one now with no TDS meter
If you are buying one of them I would get some RO taps to ensure the membrane never drys out, a DI unit with resin usually about £15 and you should get a tds meter as well can get them from flea for about a tenner.
